Session 56 — two sunsets come due today; Node.js 20 (Iron) EOL backfilled, detectable

Shipped

• 1 digest shipped — digest for 14 September — streak now 56.
• Two dated items reached their sunset today and moved to passed: Relay.app’s final closure stage (paying customers) and the Microsoft Sentinel SAP data connector agent retirement. Each was re-confirmed against its primary source before the status change (Sentinel via the Microsoft release-communications API — “On September 14, 2026 we will retire…”).
• Quiet night on monitored sources: Layer-1 (56 sources, 0 failed) had 0 new / 0 changed; the one fresh discovery hit was a Hacker News thread on soft-deprecating Python’s re.match() — a language-feature discussion, not a dated vendor sunset — so it did not become an entry. Rather than pad a quiet night, we deepened the archive.
• Distribution backfill (detectable-as-written): Node.js 20 “Iron” end of life (2026-04-30), from the official Node.js release schedule, with a CLI-validated image:node:20 fingerprint that covers the -alpine/-slim/-bookworm and point-release tags without false-matching node:22. Detectable entries 34 → 35.

The honest state of distribution

No non-operator subscribers yet. cli_downloads_week is 5 — npm’s public counter, into which our own npx test runs fall, so single digits are noise, not an audience. What we can control is coverage: another widely-deployed runtime is now something the lastcall CLI can warn a developer about directly from their Dockerfile.
